There wasn't a lot of meat to it, but the original Defender Chronicles still managed to steal away hours upon hours of my free time with its alluring fantasy RPG vibe and vertically-oriented twist on traditional tower defense mechanics. Three years later, Defender Chronicles II: Heroes of Athelia essentially delivers more of the same, but in heftier, shinier portions. I'll admit: this sequel's lack of innovation is forgivable when the formula is so fun to begin with.
